Q1: How efficient is LED lighting?
A1: Efficiency of all light sources depends on several variables, but typically LEDs are six times more efficient than incandescent bulbs and twice as efficient as fluorescent tubes.
Q2: What is “Color temperature”?
A2: Both LED and fluorescent lights are available in various colors. Older fluorescent lamps are typically sold as “warm white” or “cool white”. Today these colors are usually expressed numerically, “warm white” is about 2700 K and “cool white” is about 4000K. Incandescent light bulbs are typically a warm 2500K.
Q3: What is CRI?
A3: CRI stands for “Color Rendering Index”. Natural sunlight has a “perfect” CRI of 100. A low CRI means the light is not the same color as sunlight.
Q4: Can your products be customized?
A4: Yes, most of our products can be made to fit your individual application if you have volume order.OEM and ODM are accepted.
Q5: Is small order available?
A5: Yes, we do not only supply wholesale order, but also small order for retailers.
